Can pumps with different head values be connected in parallel?
Thread Content
One pump has a flow rate of 5 cubic meters and a head of 20 meters, while another pump has a flow rate of 7.2 cubic meters and a head of 40 meters. Can these pumps be connected in parallel? The ultimate output should be 13 cubic meters with a head of 40 meters. Thank you!
They cannot be turned on at the same time.
No, that pump with a flow rate of 5 cubic meters and a head of 20 meters will not be considered
Obviously not; if they are started at the same time, the small pump is useless.
Generally speaking, the head is equal to the outlet pressure; it is determined during the design phase of the pump, and it is difficult to increase.
It’s impossible; these two pumps cannot be connected in parallel, as doing so will cause the pump with lower head pressure to stop working or operate in reverse
They cannot be used in parallel; if operated simultaneously in parallel, pumps with low head will not be able to deliver any flow, and using pumps with low head alone will not allow the required 40-meter head to be achieved! !
Obviously, it’s not possible! As the people above have said.
It’s not possible; I recommend buying a new pump, as it has higher operational efficiency. The electricity saved each year is enough to cover the cost of buying a new pump.
It is not possible to achieve a head of 40 meters; a lower head means no work will be done, which is the same as closing the outlet valve
